Direct RNA ONT sequencing of pine roots under ammonium nutrition

ABSTRACT: Epitranscriptomics modifications constitute a gene expression checkpoint in all living organism including plants. Considering the relevance of nitrogen nutrition and metabolism for the correct plant growth and development, it can be hypothesized that epitranscriptome changes must regulate every biological process in plants including nitrogen nutrition. In the present work, the epritranscriptomics changes in maritime pine roots caused by ammonium nutrition have been monitored through direct RNA sequencing using Oxford Nanopore Technology. The main transcriptome responses to ammonium nutrition affected to transcripts involved in nitrogen and carbon metabolisms, defense response, hormone synthesis and signaling, and translation. Additionally to a global detection of epitranscriptomics marks, the m6A deposition and its dynamics have been identified, which seems to be important regulators of translation when compared with the proteomic profiles of the same samples. In this sense, the obtained results suggest that protein translation is finely regulated through the epitranscriptomics marks maybe through changes in mRNA polyA length, transcript amount and ribosome protein composition. The multiomics results in the present study suggest that the epitranscriptome must modulate the responses to development and environmental changes, including ammonium nutrition, through buffering, filtering and focusing the final products of the gene expression.

N6- methyladenosine (m6A) detection in ammonium treated seedlings through RNA immunoprecipitation

Project description:Epitranscriptomics modifications constitute a gene expression checkpoint in all living organism including plants.

In the present work, the epritranscriptomics changes in maritime pine roots caused by ammonium nutrition have been monitored through RIP-seq. The main transcriptome responses to ammonium nutrition affected to transcripts involved in nitrogen and carbon metabolisms, defense response, hormone synthesis and signaling, and translation.

Interaction between CO2 levels and nitrogen nutrition in Pinus pinaster

Project description:The main objective of the present work is the transcriptomic analysis of the interaction between nitrogen nutrition and CO2 levels in maritime pine. For this purpose, seedlings were fertilized with nitrate or ammonium and grown in two different CO2 levels: normal (400 ppm) and high (720ppm).

Proteomic profile of Pinus pinaster roots under ammonium nutrition

Project description:Ammonium nutrition was studied at short times (24 hours) in roots from one month-old seedlings of maritime pine. Control seedlings were irrigated with 80 mL of water (C) and the experimental seedlings with 80 mL of 3 mM NH4Cl. Root samples were collected at 24 hours post-irrigation and immediately frozen in liquid N. This experiment was carried out three independent times.

Comparison of root transcriptomes in Arabidopsis thaliana plants supplied with different forms of inorganic nitrogen

Project description:Plants aquire nitrogen from the soil, most commonly in the form of either nitrate or ammonium. Unlike ammonium, nitrate must be reduced (with NADH and ferredoxin as electron donors) prior to assimilation. Thus, nitrate nutrition imposes a substantially greater energetic cost than ammonium nutrition. Our goal was to compare the transcriptomes of nitrate-supplied and ammonium-supplied plants, with a particular interest in characterizing the differences in redox metabolism elicited by different forms of inorganic nitrogen. We used microarrays to compare the short-term transcriptional response to either nitrogen supply or ammonium supply in Arabidopsis roots. Genes upregulated or downregulated by nitrate only, ammonium only, or both ammonium and nitrate were identified and analyzed. Arabidopsis thaliana (Col-0) plants were grown hydroponically until they reached growth stage 5.10. They were then transferred to a nitrogen-free medium for 26 hr and then supplied with 1 mM nitrate or 1 mM ammonium. RNA isolation (and subsequent microarray analysis) was performed on root tissue isolated just before nitrogen supply (time 0) and at 1.5 hr and 8 hr after nitrogen supply (1.5 hr nitrate, 8 hr nitrate, 1.5 hr ammonium, 8 hr ammonium).

Gene expression in tissues of root tips from Pinus pinaster seedlings under ammonium nutrition

Project description:In the present study, the gene expression changes in four different tissues of root tips from maritime pine were analyzed. The roots were under two nutritional conditions (only watered or fertilised with 3 mM of ammonium) and harvested after 24 hours of the treatment.

MeRIPseq of Toxoplasma gondii

Project description:Toxoplasma gondii is an obligate intracellular parasite that can cause serious opportunistic disease in the immunocompromised or through congenital infection. To progress through its life cycle, Toxoplasma relies on multiple layers of gene regulation that includes an array of transcription and epigenetic factors. Over the last decade, the modification of mRNA has emerged as another important layer of gene regulation called epitranscriptomics. Here, we report that epitranscriptomics machinery exists in Toxoplasma, namely the methylation of adenosines (m6A) in mRNA transcripts. We identified novel components of the m6A methyltransferase complex and determined the distribution of m6A marks within the parasite transcriptome. m6A mapping revealed the modification to be preferentially located near transcription termination sites within the consensus sequence, YGCAUGCR. Knockdown of the m6A writer enzyme METTL3 resulted in diminished m6A marks, loss of a target transcript, and a complete arrest of parasite replication. Furthermore, we examined the two proteins in Toxoplasma that possess YTH domains, which bind m6A marks, finding them to be integral members of the cleavage and polyadenylation machinery that catalyzes the 3’-end processing of pre-mRNAs. Together, these findings establish that the m6A epitranscriptome is essential for parasite viability by contributing to the processing of mRNA 3’-ends.

Dissecting the rice genes responsible for long time changes of nitrogen supply forms and nitrogen starvation

Project description:In comparison with provision of either ammonium or nitrate alone, simultaneously supplying both forms of N results in superior growth and yield for the majority of plants including rice. Using a rice 22K oligo-array, we performed transcriptome analysis to identify genes of rice (Oryza sativa L. ssp. japonica) responsive to change of N-supply forms and N-starvation. Using the supply of ammonium nitrate (one to one molar ratio) as control, the total number of root genes that were equal or more than two fold up- or down- regulated was 445, 324, and 781 by upon supply of either ammonium or nitrate or continuous N starvation, respectively for 96 h. In the shoot the equivalent numbers were much smaller only 32, 58, and 165, respectively. Clustering of the rice genes associated with different environmental stresses revealed substantial organ specificity of the root and shoot to N starvation, and also to the N supply form. Genes encoding transporters for ammonium and nitrate, nitrate reductase, glutamate dehydrogenase, and aspartate amino transferase, showed great response to change of the N supply form, especially to N starvation. Some of the genes involved in chlorophyll metabolism, carbon fixation and assimilation, were enhanced by ammonium supply only, but significantly suppressed by N-starvation. In the shoot there was increased expression of more general stress genes under nitrate when compared to ammonium nutrition. In the root the reverse situation was true with more apparent stress under ammonium nutrition. The microarray approach has revealed new levels of complexity in the response of rice to the form of N supply.

Transcriptomic response of tomato (Solanum lycopersicum) plants to ammonium toxicity at elevated CO2 conditions

Project description:This work aims to study the effect of the elevated CO2 concentration on the tomato plant response to the toxicity provoked by ammonium nutrition. Tomato plants (Solanum lycopersicum L. cv. Agora Hybrid F1, VilmorinÂ®) were grown for 4 week with 15 mM of nitrogen, supplied as nitrate or ammonium, at ambient or elevated CO2 conditions (400 ppm or 800 ppm). Transcription profiling by array was carried out in roots for the four growth conditions assayed and gene expression comparisons were done between N sources and CO2 conditions: i) genes differentially expressed in response to the atmospheric CO2 concentration (800 ppm vs 400 ppm CO2) under nitrate or ammonium nutrition; ii) genes differentially expressed in response to the N source (ammonium vs nitrate) under ambient or elevated condition. 3 biological replicates for each growth condition were analysed.CO2).
